Subject[2.6 patch] parisc: "extern inline" -> "static inline" (fwd)
"extern inline" generates a warning with -Wmissing-prototypes and I'm 
currently working on getting the kernel cleaned up for adding this to
the CFLAGS since it will help us to avoid a nasty class of runtime
errors.

If there are places that really need a forced inline, __always_inline
would be the correct solution.
